Yes, i did enter G91 before axis movement. But nothing was changed, axis didn’t move.

when we connect the motors individually and give home all command they work as expected but when connected all three of them only Z works.

Sorry for confusion and inconvinience,
The DM542 driver were used in our premises for checking if there any problem in the coding, here no issues were faced while giving the command.
But now while using the PAS2-4536-1.5N driver at clients place for the X-motor ,the Y-motor and the Z-motor individually, only the Z-axis motor responds while commanding.
I have also tried connecting each motor to diffrent ports on the expansion board even then only the z-motor work on any port connected.
On giving 5V supply all the motors lock and does not respond on commanding.

Hello,
*The first two point were covered and by doing so only one of the motor responds to the homing command(i.e z axis motor), the Y-axis motor is enabled and the X-axis motor remains disabled.
*Only one motor respond at a time when the three are connected (have checked it connecting individually).
*I have attached the config.g file below for refrence.
*When connecting PUL+, DIR+ and ENA+ from the external driver to +5V on one of the heater/servo connectors on the breakout board, instead of to the + pins on the 6-pin output connector all the motors are in enabled state and follows no commands.
*In the following config.g the motors were conneted to:
X-motor- E6 ,DRIVE-9 (on expansion board)
Y-motor-E5 ,DRIVE-8 (on expansion board)
Z-motor-E4 ,DRIVE-7 (on expansion board)

M584 X9 Y8 Z7 E3 ; XYZ AND EXTRUDE ON EXPANSION BOARD

Hello.
I am using Stepper Motor Closed Loop Driver for my XYZ axis. which require input voltage of 5 volts, but Duet 2 Ethernet only provide 3.3v output at motor. that is why i order Duet expansion breakout board.
I did all changes in config.g which are mentioned Duet3D Documentation. but now only one axis is moving.

Second step :
l take Nema 17 and DM542 Stepper Motor Driver, i did all required changes in Config.g then all axis started moving.

Why is it so..
Troubleshooting points
1.Checked Motor connections.
2.Checked wires crimping & connectivity.
3.Tried with different ports board on expansion
breakout board
Please help me..
